What effect does acid rain have on marble.

Chemical reaction three common acids that form in the atmosphere are carbonic acid that forms from carbon dioxide nitric acid that forms from nitrous oxide and sulfuric acid that forms from sulfur dioxide. How does acid precipitation affect marble and limestone buildings. Acid rain is a rain or any other form of precipitation that is unusually acidic meaning that it has elevated levels of hydrogen ions low ph it can have harmful effects on plants aquatic animals and infrastructure. Atmospheric pollutants are easily moved by wind currents so acid rain effects are felt far from where pollutants are generated.

Marble and limestone have long been preferred materials for constructing durable buildings and monuments. Aquatic settings are the most clearly affected by acid deposition however because acidic precipitation falls directly into them. After studying the hubbard brook forest and other areas researchers found several important effects of acid deposition on both natural and man made environments. When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves.

Effects of acid rain on materials. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide which react with the water molecules in the atmosphere to produce acids. Not all acidic deposition is wet sometimes dust particles can become acidic as well and this is called dry deposition when acid rain and dry acidic particles fall to earth the nitric and sulfuric acid that make the particles acidic can land on statues buildings and other manmade structures and damage their surfaces. Acid precipitation affects stone primarily in two ways.

How does acid precipitation affect marble and limestone buildings. What effect does acid rain have on marble. Stone surface material may be lost all over or only in spots that are more reactive. But acid rain can have a ph of about 5 0 5 5 and can even be in the 4 range in the northeastern united states where there are a lot of industries and cars.

Students know buffers stabilize ph in acid base reactions. The saint louis art museum the parthenon in greece the chicago. Effects of acid rain. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Acid precipitation affects stone primarily in two ways. Acid rain has a direct effect on limestone rocks that occur in soil below ground and on buildings. It is well established that either wet or dry deposition of sulfur dioxide significantly increases the rate of corrosion on limestone sandstone and marble.

Stone buildings and monuments in acid rain.
